As for the Web page, you have a number of options. You can use Visual Studio to create either a WebForms or an MVC solution. Or you can download the (now free) Expression Web application to produce a simple HTML page (not programmatically ;-), and EW also
supports creation of ASPX pages (although not code behind) and simple data-driven applications. Simply click the "New" icon to get a complete Web page shell, then position the cursor in the blank page and click "Insert|Media|Windows Media Player."
The program will ask you to point (browse) to your media file and select it. Note that browsers other than IE will require the visitor to download and install a plugin (Chrome actually says that the plugin is not supported).

To overcome this you can use the HTML5 video player. Of course, you'll want to use a video converter to convert the wmv output to a supported format... ;-)

From my understanding I can Capture from the screen with ScreenCaptureJob that outputs to a file, and to publish via http I need to use a LiveJob. I didn't find any way to capture the screen with a LiveJob, nor to publish with a ScreenCaptureJob.

I tryed first to read from the output file of my ScreenCaptureJob and publish it with a LiveJob, but I had to put a certain delay between the two jobs before the output file can be processed by the LiveJob, and this is not what I need.

I do not use the Encoder SDK myself; I use the program and its capture utility via the EE user interface. Therefore, I cannot provide you with programming assistance. I should note, however, that in the code you show above you have a syntax error in an attempt
to set the value of a member of the livejob class member collection PublishFormats. In this line...

liveJobPublishFormats.Add(publishFormat);

... There is no class (nor class member) named "liveJobPublishFormats." So, you need to separate the class name "livejob" from the member collection name "PublishFormats" with a period, like so...

liveJob.PublishFormats.Add(publishFormat);

Since you say that you "found a solution" I presume that you have since corrected this syntax error.

It is unfortunate, but true, that since MS abandoned the Expression family of programs six years ago, the corresponding forums have become more or less moribund. We're lucky to get 2 to 4 new topics a week over in the Expression Web forum, and this one is
even slower. Many seem to have moved on to other products, and you may find that no one familiar enough with the SDK to answer your question will even see it.

As I said previously, Google is your friend. Try searching various different forms of the search term "using expression encoder sdk" or "programmatically encoding with expression encoder" or other variations. You can also try
forums.asp.net and
stackoverflow.com to see if they have an answer or can point you to tutorials, etc. Good luck! ;-)

Hmm... in my last reply I was looking mainly at the code, and missed the implication of your first two paragraphs. Leaving aside that the second part of your first paragraph is exactly opposite the first half (and that it's spelled "tried," not
"tryed"), the inference to be taken from the second paragraph is that you are trying to publish a screen capture in real time. Is that correct? If so, I do not believe that that is supported. See
this thread, where an MCC, MVP, and
Microsoft employee, states that real-time capture and publish is not supported in any version of Encoder.

It is possible to set up Encoder for Live IIS Smooth Streaming, but you must have, or have access to, an IIS Server with IIS Media Services installed. Check out
this site, which explains both how to install and configure IIS Media Services into IIS and how to configure Encoder.

On configuring Encoder, BTW, note that it is done using the EE user interface, not programmatically. I do not know if the EE object model exposes the necessary methods to do this configuration programmatically. In any event, note, however, that this capability
requires Expression Encoder Pro, which, unfortunately, is no longer for sale. Even if it were, it was not cheap ($200 or more, IIRC). There are product keys for the Pro version on the Web (YouTube) which may or may not work (I've had success on one
machine, failure on another).

If I am correct in my surmise of your intention, you may want to investigate other live streaming options, such as the open source
Open Broadcaster Software. For live streaming to YouTube, there is also "How To Live Stream On YouTube,"
which uses capabilities provided by YouTube. So, if you're not wedded to writing your own application (which may not even be possible), that may just get the job done for you. Just sayin'... ;-)

Thank you very much for your response and considerations. The code I wrote was only for reference. The one I use is correct. Your info on EE and its usage are correct, I should use other technologies, but since 2014, I developped an app, first in Silverlight,
then migrated to WPF, I still use to broadcast via Youtube, basketball games.

My app has many features like twitter and facebook integration, advertising for commercial return, score and ranking online updates, integration with club's websites, up to three video source at the same time, integration with any video/audio source
in the marketplace.

What I am looking for now is to integrate this app, with all its hardware system, with a media system (amplifier plus video projector) and build a complete entertainment system inside the gym.

My objective is to be absolutely cheap and mobile (unfortunately we don't own any gym, so we must be able to mount and dismount the hardware each time, and quickly).

The actual main problem seams to be the ability to clone a video window (with sound) from one PC to another, in near real time. I thought to try publish it via http on a local dedicated WiFi network, but it seams not yet to
be the right solution, for quality weakness also, even if I tryed it with other software like ffmpeg.

May I ask what other solutions folks have move on to? I have 2 apps that use Expression Encoder SDK for capturing webcam images. Recently we've been experiencing failures on Win 7 machines and are unable to see the webcam output. That, and the extra load
of having to install expression encoder on user's machine makes me want to find another solution. I did like not having to interface directly with a camera driver in C#/WPF but I am sort of stuck now. Looking for a solution.
